Down on one knee, Nick Cannon swept Mariah Carey off her feet with a $2.5 million engagement ring. This 17 carat Jacob & Co masterpiece has a square emerald-cut pink center diamond surrounded by 58 intense pink diamonds and two half-moon diamonds on each side.

Trust Fergie to mix things up, and beau Josh Duhamel complies with a big and bold H Stern ring that is designed around a star. With a burst of stones surrounding a 4 carat diamond center, the only thing conventional about this wedding band is the additional singular 18k white gold ring.

There ain’t anything unusual about the penchant for pink amongst women, and yet Anna Kournikova’s 11 carat pink engagement ring would have you do a double take. Maybe it’s the OTT pear-cut design, or the fact that this enormous rock defies the delicacy that is synonymous with engagement rings—have a look and you will know what we mean.
